Tom--it may be my imagination, but I almost remember something about somebody 
crossing Siberians with I. missouriensis.  Would this even be a possibility, 
or am I just nuts?  It would certainly be interesting!

Barb, in Santa Fe, with designs on all the local I. miss. populations.

Yes, I think that's so...but "sooner" is measured in terms of seedlings
produced, not years. Unless there gets to be as much interest in breeding
Siberians as there has been in breeding TBs, we have many, many years of
new and exciting Siberians to look forward to!

Also, the best time to bring in different species into the mix is before
the line becomes too "refined". As someone remarked, adding different
bearded species (or historics with different genes) to one's TB lines today
is effectively commercial suicide...it takes to long to regain the "modern
look" that buyers expect. It's not too late for commercial hybridizers to
broaden the gene pool of Siberians, although it will be before long. Too
bad there aren't more species to draw from.

Happy irising, Tom.
